ANY INFORMATION A HACKER CAN OBTAIN ABOUT YOUR SYSTEM IS TOO MUCH INFORMATION. Broadcasting your Web server's identity via HTTP header data makes it easy for potential intruders to complete their first hacking task: identifying your OS and Web server. Hacker pre-attack reconnaissance accounts for 40% of all Internet attack traffic, so make sure that your Windows Web server isn’t giving away unnecessary clues about its identity. SERVERMASK SOFTWARE FROM PORT80 SOFTWARE MODIFIES YOUR WEB SERVER’S "FINGERPRINT" by removing unnecessary HTTP response data, modifying cookie values, and obscuring other response information, thus masking the identity of your server. Advanced options include custom header creation, Apache emulation, response randomization, a Remove Any Header feature, cookie masking, and one-click WebDav disabling. PART OF A TOTAL SECURITY STRATEGY FOR WINDOWS-BASED WEB SERVERS, ServerMask software provides camouflage to augment the armor provided by firewalls and intrusion detection systems (IDS). Not only does successful obfuscation discourage attacks in the first place by making your Windows server less conspicuous, but it also makes hackers more likely to trigger IDS through misguided exploits. ServerMask is already used by thousands of customers, including financial institutions, governments, and corporations concerned with security best practices, and has been hailed as "clearly the best solution yet produced for managing the IIS Server banner." INSTALLED IN MINUTES AS A SUPER-FAST AND STABLE ISAPI FILTER, ServerMask is fully compatible with IIS 4, 5, and 6, IIS Lockdown, URLScan, FrontPage, Outlook Web Access, and major scripting platforms like ASP, ASP.NET, ColdFusion, PHP, and Perl. ServerMask is available for a free, fully functional 30-day trial and includes free technical support.
